I am a little confused by your wife's actions (telephone calls you wrote about), reading your description of your marriage I am also wondering what on earth went so wrong? Did you both talk about seeking counselling? The first step in the divorce is the petition and then the Decree Nisi, which is probably the sitting on the 10th March you speak of. I am not one to advocate false hope but before this there is still a chance of you both seeking reconcilliation - I feel very strongly about people doing EVERYTHING they can before heading for divorce... that way there can be no recriminations at a later date. Have you tried writing to your wife, not suggesting grovelling here, just writing - that way she will have time to read and digest/deal with things - then suggest meeting up. It seems you are not angry with each other - just sad that this is happening - but what I don't understand is that if you both feel like this why can't it be put right?
I am trying hard not to interfere but I can feel your sadness coming across and I just want to try and help!
